similar manga?

So I watched Gantz less than a week ago, then I decided to read the manga, and its even better than the anime. However I am almost caught up so I need something new to fill my time. Are there any manga that are similar to Gantz as far as sheer awesomeness goes? The two that seem the most interesting from my lesser manga knowledge are Death Note and D. Gray-Man. Any manga that includes attractive mostly (or completely) naked women, violence, and a decent plot (probably the most important) would be great. So yeah, any suggestions?

Im sorry =/. I tried to look around first and found D. Gray-Man and Death Note to be interesting, I guess that was not sufficient. I'll do my best not to waste everyone's time for now on with posts like this. Thanks for everyone's responses though, now I have quite a bit of downloading to do.
